Patent JP-S6181027-A (JP)
Title: Pll circuit
Inventor: KISHINO AYANORI
IPC: H04L7/02
Filed: 1984-09-28
Abstract: PURPOSE:To shorten the pull-in time at changing a lock frequency time by generating a bias voltage which acts to approximate the oscillated frequency of a voltage control oscillator to a lock frequency after change in response to the change of the lock frequency and applying this voltage to the voltage control oscillator when the lock frequency is changed. CONSTITUTION:A bias voltage control 8 is controlled together with a frequency divider 4 on a basis of channel set information from a channel setter 7 and shifts the bias voltage of a VCO3 to a value corresponding to the frequency of the channel in response to channel setting of the channel setter 7. Thus, the output frequency of the VCO is momently to a new lock frequency in response to channel setting, and the pull-in time is shortened.

Title: Remote control system for disconnecting power supply
Inventor: SUGIZAKI HARUO
IPC: G06F1/00
Filed: 1982-11-22
Abstract: PURPOSE:To disconnect power supply to an information processor under remote control securely by allowing the opposite information processing centers to confirm mutually whether a power-off indication signal and its answer signal are received by the opposite side or not. CONSTITUTION:A host-side CPU2 once sending out the power-off indication signal starts monitoring the time and waits for an answer regarding whether a power-source disconnection is possible or not from an information processor 7 for a specific time. If there is the answer within said time, it is certain that the indication signal is received by the processor 7, so the control is completed. When there is no answer, it is possible that the indication signal is not received by the processor 7 accurately, so the indication signal is sent out again and said operation is repeated. The processor 7 under remote control once receiving the indication signal checks the state of its system to judge whether the power source can be turned off or not and sends the result to the CPU2. The time is monitored after the answering and the processor performs the same operation with the CPU2. Thus, the transfer of the indication signal is performed securely.
